Frequently asked questions

TCM is an electronics repair lab in Zahlé, Lebanon. It carries out board-level repair and microsoldering on televisions, audio equipment, home electronics, game consoles, power and inverter systems, and tools and instruments. TCM is also known on TikTok (@tcm.lb) for testing and reviewing tools and equipment.

The fastest way to reach TCM is a direct message on TikTok at @tcm.lb. Send a short description of the fault and a photo or video of the device, and you will get an answer there.

TCM is based in Zahlé, in Lebanon's Beqaa Governorate. It serves Zahlé and the wider Beqaa Valley, and takes on work from across Lebanon.

TCM repairs televisions, amplifiers, speakers and audio gear, home appliance control boards, satellite receivers, game consoles, UPS and inverter systems, chargers and power supplies, power tools, battery packs, and measuring and workshop equipment. The work is done at board level: individual failed components are replaced on the circuit board rather than the board being swapped out.

No. TCM is an electronics repair lab, not an IT or computer shop. Phones, tablets and laptops are the one category not handled here. Everything else electronic is, from televisions and audio equipment to consoles, inverters and power tools.

Often, yes. A device is usually called unrepairable because the shop replaces boards rather than repairing them, and for older equipment a replacement board may no longer be sold at all. TCM diagnoses at component level, so faults like a shorted supply rail, a burnt driver IC or a lifted trace are repairable here even when a board swap was the only option elsewhere. A second opinion costs you nothing but the message.

Usually yes. Board-level repair does not depend on the manufacturer supplying a replacement board, because the components on that board, the capacitors, power ICs, drivers and connectors, are standard parts that are still made. That is why equipment well past its support life can often be brought back at TCM when a parts-based repair has nothing left to offer.

Yes, and both are common here. Liquid-damaged boards are cleaned ultrasonically to remove corrosion, then inspected under a microscope so the components the liquid actually destroyed can be replaced. Surge damage is traced the same way. In both cases the sooner the device is brought in and left switched off, the more of it survives.

Price depends on the device and on what actually failed, so TCM quotes only after the device has been inspected, because a guess before diagnosis is not a real price. Message TCM on TikTok with the model and the symptom for an estimate, and you will be told the cost before any work begins.

TCM tests and reviews tools and equipment on TikTok at @tcm.lb, judged from a repair bench rather than an unboxing table: how a tool is built inside, what tends to fail on it, and whether it can be fixed when it does.

Because the two do different work. A shop identifies the failed module and orders a new one. A lab finds the failed component on that module and replaces it. The lab route is cheaper, it keeps equipment alive that no longer has spare boards being made for it, and it is the only option at all for a great many faults.
